Sectional and continuous seeding integrated depth-adjustable multifunctional seeder

Abstract

The invention relates to a sectional and continuous seeding integrated depth-adjustable multifunctional seeder, and belongs to the technical field of seeding apparatus manufacturing. The seeder comprises a sectional seeding device, a continuous seeding device, a transfer mechanism, a seed throwing head mechanism, a seeding depth adjusting device, a travel switch and a control device; the sectional seeding device, the continuous seeding device and the transfer mechanism are arranged above a working platform in a parallel manner, the seed throwing head mechanism is arranged under the working platform, a seed supplementing seat is arranged behind the working platform, the travel switch is arranged at one side of the frame of the seeder, the seeding depth adjusting device is arranged at the bottom of the frame of the seeder, the control device is arranged in the middle portion of the frame of the seeder, and the control device, a fifth wheel instrument, the travel switch, the sectional seeding device and the continuous seeding device form feedback connection. The seeder has the advantages of uniform seed distribution, accurate seed falling, rand setting of the length of a small zone, realization of sectional and continuous seeding integration, and enlargement of the application range of seeders.

Description

technical field [0001] The invention belongs to the technical field of sowing equipment manufacturing, and relates to a sowing machine, in particular to a depth-adjustable multifunctional multifunctional sowing machine integrating segmented and continuous sowing. Background technique [0002] Seed engineering has always been the focus of the world's economic work. As a country with a large population, it is particularly important for our country to cultivate excellent varieties, increase food production, and ensure food security. As early as 2010, the central government's "No. 1 Document" had already emphasized that "the focus of agricultural science and technology should be placed on the cultivation of improved varieties". For the cultivation of new varieties of crops, the quality of the experiment is the most important thing. Therefore, a self-propelled numerical control plot seeder with high degree of automation, accurate sowing, stability and reliability has become a pop...

AI Technical Summary

Problems solved by technology

Domestic seeders have a great price advantage, but due to the transmission mode of mechanical sprockets, gears, chains, belts, and bottom wheels, there are large errors in data transmission when transmitting power, resulting in the rotation speed of the seeding disc being different from that of the drill. The driving speed of the machine does not match, which eventually leads to uneven sowing amount in a single plot and a single row length, and the beginning and end of sowing are not at the predetermined location, which cannot meet the predetermined requirements, resulting in large errors in the accuracy of the test.

At the same time, it is cumbersome and complicated to use, the transmission is fragile, the efficiency is low, and the accuracy is poor

Although the overall quality of imported seeders has been greatly improved compared with domestic seeders, there is no improvement in performance and the price is extremely expensive.

The seeders mentioned above all adopt the transmission mode of mechanical sprocket, gear and chain, and the data transmission error is relatively large; the design of the seed distribution head is rough, and the seed distribution is uneven; the seeding location is judged by visual inspection and manual seeding, which cannot reach the fixed point Seeding; the sowing length is capricious with the change of the soil structure, and the plots are often mixed, which leads to the scrapping of the test; the sowing length adjustment gradient is too large, and there are many blank lengths. The test arrangement is restricted by the performance of the seeder, and scientific experiments cannot be carried out effectively; the sowing depth The adjustment is rough, and small quantitative adjustments cannot be made due to the soil conditions; the depth of the soil is extremely unstable, the sowing is too deep, and the phenomenon of exposed seeds often occurs; the front and rear of the machine are too long, and the turning radius of the U-turn is too large, which wastes land; the driving position is unreasonable and the field of vision is poor. , there is a blind spot for observing the surroundings of the machine, which poses a great potential safety hazard
